Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithm", "_ optimized algorithms"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimisation algorithm", "_ approximation algorithms"
"post optimized algorithm" » "post optimized algorithms", "post optimizer algorithms", "most optimized algorithm", "cost optimized algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ estimation algorithms") OR ("_ optimization algorithms"))) OR ("post optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ estimation algorithms\") OR (\"_ optimization algorithms\"))) or (\"post optimized algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ estimation algorithms ) OR ( _ optimization algorithms ))) or ( post optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithms") OR ("_ optimization algorithms"))) or ("post optimized algorithm"))*.
